How hard is starting directory site?

[copper]

Hi,

I am thinking about starting a directory site

How difficult is getting initial submissions?
How do I get initial submissions?

I am considering the domain "QV.net" for it.

• I could go with general directory with "Quo Vadis - where are you going" or...

• Quality Vacations - Travel, vacation specific directory or...

• Quality Videos - video related directory or...

• Really specific "Queen Victoria Village, also known as QV" in Australia directory.
  They have shopping center called "Queens Village" and they use QV.com.au

Which directory would you choose?

Thanks in advance
